In a nuclear fusion reaction, the mass of the reactants is the mass of the products.

a) less than
b) more than
c) the same as

Nuclear fusion reaction is a reaction in which two or more atomic nuclei come close enough and form one or more different atomic nuclei and subatomic particles (neutrons or protons). During the nuclear fusion reaction a huge amount of energy is released. A fraction of the mass of the reactants is converted into energy.According to this in a nuclear fusion reaction, the mass of the reactants is more than the mass of the products.

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
